    The final result, with the conjunction of the thermoregulable anti-fogging system by microcontroller, object of the invention, is to have a seemingly standard rigid endoscope (FIG 4), able to withstand the continuous changes of temperature during the surgical intervention, adding value to the Endoscopy device and avoiding common fogging. With this thermoregulable anti-fogging system it is possible to control the temperature levels, thus being easy to avoid fogging/fogging inside any intervention where a rigid endoscope is used, such as hieroscopy, cystoscopy, general surgery, arthroscopy, ... With this invention, it is completely avoided that the surgeon has to remove the endoscope in full intervention from the patient's interior. This entails the absence of fatigue in the surgeon due to the continuous impossibility of vision. This will reduce the duration of the intervention, optimizing the process and providing the quality of vision provided for the endoscope in question.

    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] The present invention belongs to the field of medical-surgical equipment and more specifically to that of minimally invasive surgery.
    [0007]
    [0008] The main object of the present invention is a thermoregulable system by microcontroller, which is implemented in the manufacturing process, of any rigid endoscope. Through which we can control the temperature levels of the distal end, in order to avoid fogging / fogging during all types of interventions where a rigid endoscope is used, such as in hysteroscopy, urology, general surgery, arthroscopy, etc ...
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] Endoscopic surgery is a standard and safe medical technique today. It is a surgical technique that is practiced through a natural orifice, a surgical incision or a lesion, for the visualization of a hollow organ or body cavity. Using the assistance of a video camera that allows the medical team to see the surgical field inside the patient and intervene in it. Through the fiberglass, light is transmitted for illumination and visualization without transmitting harmful heat.
    [0013]
    [0014] These minimally invasive techniques are called, since they avoid the large scalpel cuts required by open or conventional surgery and therefore make possible a much faster and more comfortable postoperative period.
    [0015]
    [0016] EXPLANATION OF THE INVENTION
    [0017]
    [0018] The present invention is a thermo-adjustable anti-fogging system by microcontroller, this system is implemented in the manufacturing process, of any rigid endoscope By which, its temperature is controlled so that in no case the endoscope becomes fogged during the intervention.
    [0019]
    [0020] This invention may be applied in any type of endoscopic surgery, in which an optician is inserted into a cavity of an organism, human or animal. This makes endoscopic surgery its field of application. Overcoming the difficulties of loss of vision of the surgical field caused by fogging, until today unresolved.
    [0021]
    [0022] The fogging of the optic tip or distal end is caused by the temperature difference between the two faces of the tip glass. The air has a capacity to retain moisture in the form of vapor that is directly related to the temperature. Thus, a volume of air that retains a certain volume of water vapor, when cooled, will diminish its capacity of retention and the surplus of moisture will condense. The film of air that is in contact with a cold surface is forced to get rid of surplus moisture and it is this condensation that fogs the glass of the optic.
    [0023]
    [0024] They cause fogging of the lens:
    [0025] - The low temperature of the insufflated gas (C02), which is used in certain surgeries such as gastric surgery.
    [0026] - The patient's own body temperature.
    [0027] - The humidity existing within the surgical field due to the presence of body humors.
    [0028] - The interaction of the surgical instruments and the endoscope.
    [0029] - External variables.
    [0030]
    [0031] Currently in the surgical practice, the fogging of the lens is fought in two different moments:
    [0032]
    [0033] Before the intervention.
    [0034] - Immersion of the optics in hot serum at 50 ° C before introducing it into the cavity, to heat its walls and prevent it from being a cold surface, on which steam condenses.
    [0035] - Increase the CO2 temperature through a heated insufflator duct.
    [0036] During the intervention;
    [0037] - Application of anti-fogging on the tip of the optics, such as isopropyl alcohol, and other products on the market.
    [0038] - Manual cleaning of the lens using gauze and immersion of the endoscope in hot serum at 50 ° C.
    [0039] - Introduction of the distal tip of the endoscope in auxiliary heat devices.
    [0040]
    [0041] However, these are only transient solutions, since at the moment when the optics lose temperature, the fogging of the lens will occur again.
    [0042]
    [0043] These unresolved difficulties cause:
    [0044] - Loss of vision in the surgical or examined field.
    [0045] - Loss of time during the intervention caused by the continuous repetitions in the extraction and insertion of the endoscope in the body during the intervention to defuse it and continue with the surgery or medical examination.
    [0046] - High cost in fungible CO2 probes
    [0047]
    [0048] The main advantages of this invention are the following:
    [0049]
    [0050] - The surgeon will always have a clear vision. As you can control the working temperature of the endoscope in a range between 30 and 50 degrees Celsius.
    [0051]
    [0052] - Avoid continuous repetitions in the extraction and insertion of the endoscope in the body of the patient during the procedure to demist and continue with the surgery or medical examination. What is a significant reduction in the time of intervention, because you do not have to perform continuous maneuvers demisting the same outwardly. Likewise, there is greater control over the possible hemorrhages that may arise during the intervention.
    [0053]
    [0054] - Lower cost of consumables, thus having a significant economic savings. In the case of using the heated CO2 insufflator, since the (fungible) probe used is single-use and has a high economic cost.
    [0055]
    [0056] - The endoscope, once this anti-fogging system is installed, does not change the size, length or weight of a standard endoscope. So it is not necessary to change the instruments of the operating room. As for example the trocars.
    [0057] - It is possible to correct external variables that are difficult to control that directly affect the time and result of the operation: The surgeon avoids the fogging that the environmental conditions of the operating room can produce. The use of other surgical instruments that are inserted into the patient's body simultaneously with the endoscope, such as cauterizers, or any other instrument that can generate heat. All this instrumental generates heat inside the cavity in which it is intervening, which comes to condition directly in the time of vision before the lens is fogged. As well as the patient's own anthropometric characteristics.
    [0058]
    [0059] DESCRIPTION OF THE INVENTION
    [0060]
    [0061] The anti-fogging thermocontrol system, object of the invention, consists of installing an electrical resistance of nichrome (nickel and chromium alloy) insulated with a tape resistant to high temperature in the inner tube. This resistance is adjustable in temperature working in a variable range between 30 and 50 degrees Celsius. Thermo regulation is achieved by microcontroller installed in the light source.
    [0062]
    [0063] The resistance is coupled on the surface of the inner tube of the endoscope, ending at the distal end radially. This resistance receives the electricity through a connector located in the body of the endoscope. What makes the feeding of the light fibers of the endoscope and the anti-fogging system independent, although both are connected to the light source.
    [0064]
    [0065] BRIEF DESCRIPTION OF THE DRAWINGS
    [0066]

    [0073]
    [0074] PREFERRED EMBODIMENT OF THE INVENTION
    [0075]
    [0076] In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed, which comprises the parts and elements that are indicated and described in detail below.
    [0077]
    [0078] The architecture of a rigid endoscope consists mainly of 4 parts:
    [0079]
    [0080] - External tube (11)
    [0081] - Body (12)
    [0082] - Eye piece (13)
    [0083] - Light post (14)
    [0084]
    [0085] The external tube (11) houses the inner tube (2) where the lenses (7), separators type 1 (8), separators type 2 (6) and the objective system (5) are located. Between the inner tube (2) and the outer tube (11), there is the light fiber (9) and the electrical resistance (1). The electrical resistance (1) is wound to the surface of the inner tube (2) fully adhered and isolated by a tape resistant to high temperature. The light fiber (9) is therefore located on the resistance (1) already wound to the inner tube (2) thus occupying the remaining space up to the inner surface of the outer tube (11).
    [0086]
    [0087] The body (12) is the component responsible for assembling each of the subsets that make up the final product. In it, the Eye Piece (13) is collected together with the external Tube (11) and the Light Post (14). Therefore, it is the link between the sub-assemblies responsible for transmitting the vision, transmitting the light, and the thermo-controllable anti-fogging system.
    [0088]
    [0089] The eye piece (13) in its interior groups all the elements related to the vision of the proximal end. In this subset is the focusing system (10). The eye piece (13) is connected to the camera so that the image obtained by the rigid endoscope can be projected on a monitor.
    [0090]
    [0091] The light post (14) is the set responsible for housing the components related to the transmission of light. This set is connected directly to the light cable. Through this assembly the fiberglass (13) passes along the inside of the outer tube (11)
    [0092]
    [0093] The resistance (1) that is placed around the inner tube is of nichrome. Nichrome or Nichrome is an alloy of nickel and chromium. It stands out for being a metal very resistant to high temperatures and for having a high electrical resistance. Its main properties are:
    [0094] - High resistance to corrosion and oxidation.
    [0095] - High resistance to high temperatures (high melting point).
    [0096] - High electrical resistance (not as good conductor as other metals).
    [0097] - It's not magnetic.
    [0098] - Silver gray color.
    [0099] - Resistant and flexible.
    [0100] (https://www.micro-log.com/index.php controller=attachment&id_attachment=19)
    [0101]
    [0102] The temperature of the resistance (1) can be regulated by reaching a variable temperature in a thermal fork between 30 and 50 degrees Celsius. The diameter of the resistance (1) is 0.2mm the value of are 180 Q and its consumption of 1.2 W.
    [0103]
    [0104] The resistance (1) is placed around the inner tube (2), previously insulated with a high temperature resistant polyamide tape. This tape is used successfully in applications at temperatures as low as -269 degrees Celsius and as high as 400 degrees Celsius. The tape has an adhesive film to be glued to the inner tube (2) of the endoscope. It has high performance, reliability and durability, with a unique combination of electrical, thermal, chemical and mechanical properties.

    [0106]
    [0107] Once the endoscope is assembled, the resistor (1) will be connected to two pins that leave the endoscope body (12) as shown in (FIG 4) to be able to do the thermal regulation with the equipment to which it is connected .
